Standard Operating Procedure (SOP)

Phase 1: Document Discovery

1. Run batch analysis on your document directory:

   python scripts/batch_analyzer.py "your/document/folder" --pattern "*.md"
   

2. Review categorization - identify high-value files by category
3. Select priority documents - focus on strategy, financial, and legal documents

Phase 2: Document Upload

1. Go to NotebookLM (https://notebooklm.google.com)
2. Create new notebook with descriptive name (e.g., "Business Analysis Q4")
3. Upload priority documents identified in Phase 1
4. Group related documents (strategy + financial + legal) for better context
5. Copy notebook URL for querying

Phase 3: Intelligence Extraction

Ask targeted questions based on document type:

Strategy Documents:

• "What are the key competitive advantages and market opportunities?"
• "Identify implementation challenges and recommended solutions"
• "What are the success metrics and milestones?"

Financial Documents:

• "Summarize key financial metrics and projections"
• "What are the primary financial risks and mitigation strategies?"
• "What ROI and growth opportunities are identified?"

Legal/Compliance Documents:

• "What compliance requirements and deadlines must be met?"
• "Identify potential legal risks and recommended safeguards"
• "What regulatory issues need immediate attention?"

Proposals/Contracts:

• "What are the key obligations and deliverables?"
• "Identify potential risks and negotiation points"
• "What success criteria and performance metrics are defined?"

Phase 4: Action Planning

1. Synthesize insights across related documents
2. Create action item lists from identified recommendations
3. Develop mitigation strategies for identified risks
4. Establish monitoring for key metrics and milestones

Common Pitfalls

❌ Don't use for simple document reading - just use Read tool ❌ Don't upload sensitive personal data - NotebookLM is a Google service ❌ Don't expect real-time data - analysis based on uploaded documents ❌ Don't ignore file size limits - check NotebookLM upload limits ❌ Don't forget to organize documents - group related files for better analysis

✅ Always upload related documents together - better context for analysis ✅ Use specific, targeted questions - better than general queries ✅ Batch analyze first - identify high-value files before uploading ✅ Create separate notebooks - organize by project or document type ✅ Follow up with specific questions - dig deeper into insights

Best Practices

1. Batch analyze first - identify which documents deserve AI analysis
2. Group related documents - upload strategy + financial + legal docs together
3. Ask specific questions - "What are the risks?" vs "Analyze this"
4. Create focused notebooks - one per project or business area
5. Use follow-up questions - each query can build on previous context
6. Extract actionable insights - focus on what you can act on
7. Document findings - save key insights for future reference

File Type Support

Recommended formats:

• Markdown (.md) - Best for structured documents
• PDF - Reports, contracts, formal documents
• Word (.docx) - Business documents and proposals
• Plain text (.txt) - Notes and documentation

Optimal for analysis:

• Business plans and strategy documents
• Financial reports and budgets
• Legal agreements and contracts
• Project proposals and specifications
• Market research and analysis

Troubleshooting

Problem	Solution
Too many files found	Use specific patterns: --pattern "*strategy*.md"
Upload failed	Check file size limits and format compatibility
Generic answers	Ask more specific questions about business impact
Analysis too broad	Focus on specific aspects: risks, opportunities, compliance
Missing context	Upload related documents together for better analysis
Encoding errors	Scripts automatically handle Unicode issues
